To all whom it may concern Be it known that we, WILLIAM R. JnAvoNs and ARNOLD R. XVHITTAKER, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Calking-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to apparatus for producing calked joints between members of fragile material and members of rigid material, such, for instance, as the joints formed between gage tubes of liquid-level indicators and the metallic caps or fittings which embrace the ends thereof wherein the calking is accomplished by the pressing or crowding of lead or similar ductile material between the ends of the tubes and the cooperating In the performance of this operation, it is required that only suflicient pressure be applied to it to be firmly squeezed or crowded into and distributed throughout the space which it is joint, any pressure in excess of this being not only unnecessary but subjecting the tube to the danger of breakage.

It is the object of this invention to promentioned which is efficient in the accomplishment of its work; easy to operate; of simple and substantial construction; and one wherein a yielding pressure of limited force upon the calking material upon each complete operation of the apparatus.

Another object is to provide, ratus of the above character,

in an appameans within fined and supported during the calking operation, whereby their original shape is maintained.

Further objects will become apparent as this description proceeds.

Generally speaking our invention may be defined as consisting of the combinations of elements set forth in the claims annexed hereto and illustrated in one form in the accompanying drawings forming part hereof. wherein Figure 1 is a plan view of our apparatus in operative condition; Fig. 2 is a side elevation of the same; Fig. 3 represents a central longitudinal section of the apparatus in the lead to cause inoperative condition;

view, but with the parts in operative posi tion, as shown in Figs. 1 and 2; Fig. 5 is a transverse sectional view taken on the line 5-5 of Fig. 1 and looking in the direction indicated by the arrows;

looking in the direction indicated by the arrows; Fig. 7 is a perspective of thegagetube supporting means; Figs. 8 and 9 are sectional details through adjacent parts of the cap retaining and tube supporting means, the calking operation being illustrated thereby; and Fig. 10 is a perspective view of one type of liquid level gage, the joints of which Fig. 4 is a similar Fig. 6 is a similar view taken on the line 66 of Fig. 1 and are calked by the apparatus of our inven- A t1on..

In the drawings, in which like reference characters designate corresponding parts through the several views, 1 represents a rectangular frame which is supported by side members 2, it being secured to the horizontal top flanges of said members by bolts 3 which pass through said flanges and through lugs 1 which extend laterally from the sides of said frame near its corners.

Each end of the frame 1 is provided with a pair of bosses 5 which are bored to receive a pair of bars 6 which are retained firmly in place by pins 7 which pass through the bosses 5 and the said bars. ends of the bars 6 (as viewed in Figs. 1 to 4: of the drawings) project beyond the end of the frame 1 and have slidably mounted thereon a cross-head 8 within which a earn 9 is pivoted upon a pin 10. cam is adapted to cooperate with the face of a boss 11, which extends from the left hand end of the frame 1 toward the crosshead, when said cam is rocked upon its pivot by the swinging of its arm 12. operation of the cam 9 the crosshead 8 is caused to slide upon the bars 6 away from the frame 1.

Secured to the bars 6 by the pins 13, just inside the right hand end of the frame 1, is a block 14, as shown clearly in Figs. 1 and 6. A similar block 15 is slidably mounted upon the bars 6 alongside the block 14 and is adapted to be moved against and away from saidblock in a manner which will'hereinafter be made clear. A pair of plates 16 and 17 are also movably supported upon the bars 6, the former resting substantially against the adjacent face of the block 15 The left hand The face of the Upon such when the parts are in normal position. In-

terposed between the plates 16 and 17 is a cushion 18 of resilient material, preferably rubber, which is retained in place by a bolt 19 passing through the plate 17 the cushion 18, and the plate 16 and threaded'into the block 15.

Apair of tension rods 20, which are threaded at their right hand ends into the,

plate 16, pass freely through holes in the plate 17, the left hand end of the frame 1,

and through the crosshead 8 in juxtaposition port and a part of the calking means for the gage tubes, a space being provided for said tubes by the-semi cylindrical grooves 23 and 24 which are formed respectively in the upper and lower faces of the jaws and their covers (see Fig. 7). Projecting from the opposite ends of the jaws 23and 24 are semi-circular lips 25 and 26, respectively, which are identical with a pair of lips 25 and 26 which project from the opposite ends of the covers of said jaws. Lugs 27 which extend from the upper portion of the rear face of the jaws 23 and 24 carry hinge pintles 28 upon which the lugs 29 of the covers 23 and24 are pivotally supported. These pintles arerof sufficient length to permit'ilongitudinal movement of the covers with respect to the jaws, as will be seenupon an inspection of Fig. 1. The portions of the upper faces of the jaws 23 and,

' 24 which are'located at either side of the grooves 23 and 24 are provided with a series of transverse, substantially dovetailed grooves 30, that wall of each of the grooves which is toward the lip-provided end ofits jaws being vertical. The adjacent faces of the covers 23 and 24 are provided with projections 31 of a shape corresponding to the shape of the notches 30 and are adapted to occupy said notches when the 7 covers are in closed position, the width of the lower face of each of the projections being slightly less than the width between the upper edges'of the notches. The longitudinal movement previously. mentioned, which is permitted between the covers and the jaws by the length of the hinge pintles, 28, provides, for the engagement of the inclined walls of the projections and notches to produce a locking action between the jaws and their covers when the jaws are longitudinally separated. I We provide, in connection with the tubesupporting jaws and their covers, a retaining means for the caps of the gage tubes, which comprises a pair of horizontal hinged frames, each of said frames being composed of two end members 35, the rear ends of which are spaced apart and connected by a rod 36 which is reduced at each end to form shoulders against which the inner faces of the end members may abut, the ends of the reduced portions of said rod being threaded for the reception of nuts 37 which firmly clamp the end members against said shoulders. For convenience of description, the lower part of the machine in Fig. 1 will be referred to as the front of the machine and the upper part as the rear, and like terms will be employed to designate the hinged frames thereon. The front ends of the members 35 are connected in substantially the same manner, by the bars 38 which are rectangular in cross section. The ends of these bars are also reduced and threaded in a similar manner to that just described in connection with the rods 36 and carry nuts 39. The rear ends of the members 35 are reduced in width and overlap each other where they are hinged together by rivets 40. To firmly lock together the front sides of the frames which are formed by the bars 38, we provide an eye bolt 41 which is pivoted at 42 between cars 38 projecting from the front side of the lower bar 38, and the opposite end of the bolt 41 is threaded for the application of a wing nut 43 and is adapted to swing into a notch between the lugs 38 which project from the front side of the upper bar 38, directly above the cars 38. About midway between the rods 36 and the bars 38 the adjacent edges of the inner faces of the members 35 are provided with semicircular recesses which, when the frames are in closed position, form a circular recess in which the fianges a of the end caps A of the gage tubes B may be confined.

Carried by the blocks 14 and 15 beyond the ends of the jaws 23 and 24 and spaced a distance apart equal to the length of the aforesaid hinged frames are a pair of angle plates 45 which have their vertical portions slightly curved away from the jaws. These plates provide a convenient means for correctly locating-the frame and the tube carried thereby within the jaws.

To perform the operation of calking the joints at the ends of a gage tube and within the flanges of its caps by the use of our apparatus, the gage tube is first assembled by placing the caps over the ends of the tube, inserting between the adjacent parts of the tube and the flange of each cap a ring of some soft metal, such as lead. The assembled gage is then placed within the retaining frames with the caps A occupying the recesses in the end members 35 of the frames, and the frames are then securely 24 in the upper raised subsequent to the last operation of the machine.

withtheir projections 31 occupying the re- 1 cesses 30 in the upper faces of the jaws. At this time the straight sides of the projections 31 are adjacent to sides of the notches 30,-and the lips 25 and cross-head engaging thenuts 21 on the rods 26 of the covers protrude somewhat beyond the lips 25 and 26 of the jaws. The operating arm 12 is thenswung downwardly to cause the cam 9 to engage the face of the boss 11 and move the cross-head 8 away from the frame 1. The rear face of the 20 causes said rods to be moved with the cross-head, which movement is transmitted through said rods to the plate l6-to'which the ends of said rods are secured. This plate .1 6 causes a compresmovement of the sion of the cushion 18 and the transmission of a part of the movement of said plate to the plate 17. By plate 17 with the bolt -19 themovement of this plate is transmitted through said bolt to the block 15 into whichthe bolt is threaded and which block carries the jaw 24.

As the blocks 14: and 15, and consequently the jaws 23 and 24, separate, the lips 25, 25 and 26-, 26 engage the edges of the lead rings C and squeeze or press them into place between the flanges a of their caps and the adjacent surfaces of the tube B, distributing the soft metal throughout this space and producing an absolutely tight joint. Upon the initial engagement of the lips 25 and 26 with the lead rings, the covers 23 and 246*Which carry said lips are moved toward each other until the inclined faces of the projections 31 interlock with the inclined sides of the notches 30 to effect a locking of the covers in closed position. i This movement of the covers also properly alines their lips with the lips on the jaws.

It will be seen from the foregoing description that the pressure which is brought to bear upon the calking material and the parts adjacent thereto is determined by the resiliency of the cushion 18 rather than by the force that is applied to the operating handle 12, and the resiliency of said cushion should be in proportion to thestrength of the gage tube. Moreover the cushion acts as a snub- 7 her or absorber for any shock produced by a quick operation of the cam and transmits such shock to the parts which are acted upon by a constrained and'even pressure, eliminating the danger of breakage to which the tube would be subjected were the original and quicker action of the cam transmitted thereto. After the joints have thus been calked, the operating arm 12 is returned to The coversare then lowered the correspondingthe engagement of the its normal position, which-causes the cam to swingout of engagement with the boss 11, and the other parts are thereupon returned tonormal position bythe pressure ;of' the springs 22,. which are confined bethe block l5 shifts said frames to a central position or until theiropposite ends are in engagementwiththeother plate 45. When in this position,; the frames with thegage may, be lifted from the jaws, the covers thereof swinging to-open position to'permit of such removal. The frames are then opened so that the'finished gage tube may be removed therefrom.
